The eye is a pinhole camera attached to
impressive DSP post-processor and Learning
units
Light is focussed onto the retina
Electrical Impulses from the retina are
chanelled by the optic nerve to the Visual
Cortex
The Visual Cortex does a whole bunch
of smart things including filtering, object
recognition, edge detection.
In `primitive animals’ A LOT of
processing happens just behind the
retina. Frogs and Rabbits have
TEMPLATES for spotting birds of prey.
Our motion sensitivity is better at the
periphery of vision than at the centre.
